Creating delicious Grilled Huli Huli Chicken is simple if you follow these clear steps:

1. Prepare the Marinade: In a mixing bowl, combine soy sauce, brown sugar, pineapple juice, ketchup, rice vinegar, vegetable oil, garlic, ginger, black pepper, and red pepper flakes. Whisk until well blended.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring it’s well-coated. Seal the bag or cover the dish and refrigerate for at least 20 minutes, or up to overnight for more flavor.
3. Preheat the Grill: Preheat your grill to medium-high heat.
4. Grill the Chicken: Remove the chicken from the marinade (discard the marinade). Place the chicken on the hot grill. Cook for about 6-8 minutes per side, or until the internal temperature reaches 165°F (75°C).
5. Char for Extra Flavor: For an additional charred flavor, rotate the chicken 90 degrees halfway through cooking each side.
6. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for 5 minutes to retain its juices before slicing.
7. Slice and Serve: Slice the chicken and serve it on a platter, garnished with green onions or sesame seeds if desired.

These steps ensure that you create an incredible meal that will leave your guests asking for seconds!
